You have to love a post that starts with "a colleague of mine".....immediately it is second hand information.
I leave this to all you pleasant people in Towers around the UK to respond.
I'm more than a little interested in which "ATSU" you refer to, and what the traffic situation was. Was there going to be an infringment towards an approach path or climb-out? The ANO definition is there, however there may be daily situations where accomodating this may be unfeasible. Please feel free to disclose where it was and who knows, there may be somebody floating around here who might be able to give you the other side of things.
P.S. B-L, taking those congeniality pills again dude?
